Title: Image forming apparatus for scanning documents larger than a flat glass.
Inventor: LEE BYOUNG BAG
IPC: H04N1/04
Filed: 2009-11-03
Abstract: Image forming apparatus 100 for scanning a document 140 having a larger size than a flat glass 110 (platen) and scanning method thereof. The apparatus includes a motor 230 to drive a document transferring roller 220; a scanner 312 which scans a first region of a large-sized document 140 loaded on the flat-glass and outputs a first image data and also scans a second region of the large-sized document transferred by said roller and outputs a second image data; and an image composing part which performs a matching of image patterns by overlapping an overlaid region selected from the first and second image data. The image composition (stitching) involves the processes of: noise reduction by Gaussian blurring before Harris corner detection, forming local descriptors, and erroneous corresponding relations elimination. Therefore A3 documents are scanned using scanning sensors of slightly larger size than A4 documents, obtaining high quality composed A3 images.

Title: System of Electrically Indicating on Board Ship the Depth of Sea Water.
Inventor: KAWAKITA YOSHINAO
IPC: G01C13/00
Filed: 1918-06-25
Abstract: 121,434. Kawakita, Y. June 25, 1918. Sounding-apparatus.-Electric means for indicating the depth of sea water comprises three electrodes placed on the ship below sea-level at unequal distances apart to form two branched circuits supplied with an alternating current which is kept at constant value, and a current meter which is affected by the difference in the currents traversing the branched circuits arising from the proximity or otherwise of the bottom. The electrodes a, b, c are attached to the side of the ship below the sea-level s, s. Two of the electrodes a, b are close together, while the third electrode c is as far as possible from the electrode a. The terminals 1, 2 are connected to a source of alternating current of which the voltage and frequency are kept constant, an automatic or semi-automatic current regulator 3 and an ammeter 4 being placed in the lead from the terminal 2. The current through the ammeter 4 branches to the primary windings 5, 6 of a differential transformer, the secondary 7 of which is connected to a current-meter 13, while the iron core 9 is moved to balance the action of the primary windings on the secondary. An adjustable resistance 8 in the winding 6 also serves this purpose, the balance being indicated by a zero reading of the meter 13. The primaries 5, 6 are connected to the electrodes b and c respectively. In a modification, the adjustable resistance is omitted. In a second modification, shown in Fig. 3, one of the branched circuits includes a fixed resistance 11 and adjustable resistance 10, while the other includes a fixed resistance 12, the meter 13 being connected up as shown. The current meter 13 may be a sensitive alternating-current meter, or it may be replaced by a rectifier and a sensitive direct-current meter in series or by a direct-current meter and a commutator in series. A balance is first obtained in deep water by adjustment of the core 9 and resistance 8, Fig. 1, or by adjusting the resistances shown in Fig. 3. On coming into shallow water, the balance is disturbed owing to proximity of the ground. The reading of the meter 13 is a measure of the influence of the ground and thus of the depth, or if a new balance be obtained the adjustment of the resistance is a similar measure. The current meter may be calibrated in known depths and may read in fathoms.

Abstract: 889,807. Rotary wing aircraft. McCARTY, L. C. March 26, 1959 [April 21, 1958], No. 10559 /59. Class 4. A rotary wing aircraft has flexible rotor blades each wound on a drum attached to the rotor head by arms and provided at its tip with a propulsion unit, such units being the sole source of power during powered flight of the aircraft, whereby the blades, when rotating, may be extended to operative, positions. The aircraft comprises a rotary hub 10 mounted on a fixed pylon 12 attached to a fuselage formed as an aerial crane, and consisting of landing gear 50, a tail boom 52 carrying a tail rotor, jet nozzle or other anti-torque device 48, and a compartment 54 secured to the tail boom to house a pilot. A fixed arm 16 and hinged arms 18 and 20, which may serve.as fuel tanks, form .part of rotor head 10 and they are inter-connected by actuators 28, 30 which are used to vary the lay lead attitude of the blades. The outer end of each arm carries a pivot 35 for reel assemblies 34 comprising spaced arms 66 each of which terminates in a projection 68 for engagement with a recess 70 in the nacelle 36 of a power plant, which as shown may drive a propeller 124 or may be a turbo-jet unit. Each pair of arms 66 carry a pivot 64 for a reel 88 on which is.wound a flexible rotor blade 74, the drum.being rotated for extension and retraction of the rotor blade by a motor (not shown) operating through a worm and worm gear 78. Longitudinal reinforcing filaments are embedded in each blade together with a fuel line 100 and electric leads 102. Lag-lead movements of the blades, when extended, are sensed by a roller device (not shown) which automatically varies the power output of the appropriate power plant or adjusts the appropriate actuator 28, 30 to correct the condition. The blades, are provided with trailing edge control .surfaces (not shown) for trimming purposes and main control surfaces 130 are provided at the rear of each nacelle whereby the cyclic and collective pitch of the blades may be varied. The pilot controls the aircraft in azimuth by adjustment of the antitorque rotor 48 by means of a hand control, but control in pitch and yaw is achieved by movement of a platform on which he stands, the platform being spring biased against movement on a central pivot. Each rotor blade comprises outer skins of impregnated fibreglass which sandwich a filler of foam .plastic. Although a crane type of aircraft, with a lifting sling 134, is described, the invention may be applied to rotary wing aircraft .having conventional fuselage arrangements.

Filed: 1940-06-19
Abstract: 543,974. Ropes of cellulose esters or saponified cellulose esters. FINLAYSON, D. June 19,1840, No. 10573. [Class 2 (ii)] Ropes of high tensile strength, flexing life, and wear resistance are made by cabling an assembly of strands made from filaments of cellulose acetate or other cellulose ester which have been stretched while under the influence of a softening agent. The filaments may have been saponified after stretching so as to convert them into continuous filaments of reconstituted cellulose, and they may have been subjected to a shrinking operation after the stretching. The filaments may be employed in the form of continuous filaments or of strands made from staple fibre. Continuous filaments within the heavy strands from which the cabled structure is derived may have but a small twist. In forming the rope the strands may be laid regularly by use of an egg-shaped tool with equi-distant grooves in its polished surface. Sizing and oiling may be effected after applying the closing twist. The ropes may be treated with a preservative, e.g. copper naphthenate. This may be applied in a solvent such as motor spirit together if desired with a lubricant.

Filed: 1926-04-27
Abstract: 273,852. Siemens Bros. & Co., Ltd., and Humphries, H. E. April 27, 1926. Automatic exchange systems. - An inter-exchange trunk is maintained non - selectable after the release of the outgoing selector for a period sufficient for the release of the switches at the. incoming end by means of a slow-release relay J in the testing-in circuit which energizes upon seizure and connects in its normally short-circuited highresistance winding. This prevents the energization of the test relay T of another selector attempting to seize the trunk after release of the connection before the relay J has fallen back. As shown in Figs. 3 and 4, the test circuit also includes the a wire of the trunk, so as to prevent seizure of a trunk which is faulty in certain respects or which terminates in a faulty selector. Impulses are sent over the b wire and the answering supervisory signal is repeated over the a wire by relay YA. Metering arrangements of the kind described in Specification 200,928 may be employed. Relay J may also control a statistical meter, and prevent hunting when all outgoing trunks are busy.
